Specification of Letters IPatent. Sept,rjjpllgjlr,

Application filed September 27 1917. Serial No. 193,418. Y Y' so that the complete mattress will have thev appearance of a mattress of ordinary construction. v

The appearance is not all the important. factor however, as the construction as` to be later described will give to the mattress all of the features foimd in mattresses of the long approved type. Y iv The construction and operation of my de-v vice will be fully set forth as the'specication progresses.

The following'is what lI consider a good and The accompanying drawings should 7be referred to for a complete understanding of the case.

Figure 1 is a perspective view of the interior casing with one of the pneumatic members in position.

Fig. 2 is a view in perspective of a completed mattress. Y

Fig. 3 is a sectional view of a portion, this section is viewed lengthwise of the mattress.

Fig. 4 is a sectional view .of a portion, this view being taken at right angles to the view shown in Fig. 3. i

Similar reference numerals indicate like parts in all the ligures where they appear.

My mattress shouldhave an inner casing and an exterior casing or cover, and while the exterior casing should be made of ticking, duck, or other comparatively fine or decorative material, the interior may be made of coarser material. y

The interior casing is oblong in shape and may be considered as formed with sides 1 and 2, and ends 3 and i. Through the end 1l, I produce a plurality of perforations for a purpose that shall appear later. Y

Secured to the ends 3 and 4L and subdividing the interior casing into three longi- ALBERT JOSEPH Y tweenv each pair may be of the same material as the exterior walls of the casing.

High up on the barrier 5, I secure aplurality` of straps 7, 8, 9 and 10 and the other tudinal chambers are barriers and 6, which end of each of these ystraps is connected to the barrier 6. f

A second series ,of straps 11, 12, 1 3 `and 14: are similarly secured.' andwdirectly 4under the straps 7, 8, 9 and 10. Thesestraps serve to sub-divide thelongitudinal chamber betweenl the barriers 5 and Gf into a plurality of compartments andthe other longitudinal chambers before-'referred tol areV also similarly divided, the straps being secured to the barriers andV to the outer walls at a point slightly lower than; the exposed edge of the barriers or walls.

When the interior casmg'iscompleted as described I place a rubber tube such as the v tube 1,5 longitudinally in each` of the longitudinal compartments passing this tube between the opposed straps 7 and 11 and be- A of opposed straps in its longitudinal compartment. The tube V15 is providedV with a the tubes are in place with their valves projecting through the perforations in the end wall 1I insert the interior easing just described into the exterior casing 17 shown in Fig. 2 and I then inflate each of the rubber tubes. When roperly inflated the flap 18 of the casing 17) is secured by means of the buttons 19 and 20 of which there is vrelative seri-es Vupon the flap and upon the valve 16 and when all of I desire to call particular attention to certain most important featuresv found 1n my mattress.

Each rubber tube is larger in diameter and longer than the compartment into which itis to be introduced, and therefor when inflated the upper and. lower portions of the tube will overlap the straps as shown in Fig. l

and will also overlap the barriers as shown in Fig. 3.

Upon the position that when the outer casino" is in pobe snapped` together sition the buttons may barriers 5 and .6 or upon all in- I termediate barriers and approximately adja- Y portion of a snap button as' and Will impart to the outer casing the t ted appearance of an ordinary mattress.

Should a tube become punctured ordeiiated it may be removed for repairs or inflated independently of the other tubes.'

The outer cover may be removed, Washed and returned as often as desired and the entire mattress may be disassembled for cleaning and re-assembled Without difliculty and Without the requirement of mechanical skill or ingenuity. Y

The size and shape of my device may be varied at Will, I may use a greater or less number of tubes, or a greater or less number of barriers and straps. @ther modiiications may be made Within the scope of theappended rclaims Without departing from the principle or sacrificing the advantages of this invention.

-Having carefully and fully described my invention What I claim and desire to secure by Letters Patent is l. A mattress having a casing, ai plurality of barriers extending longitudinally thereof and a plurality of Vstraps arranged transversely of said casing and a pneumatic member for each said longitudinal portion and received under said straps.

2. A mattress having a longitudinal casing formed of four complete Walls, one of Copies of this patent may be obtained for ve cents each, by addressing the Commissioner said Walls being provided With a plurality of perforations, a plurality of barriers secured in said casing and extending longitudinally thereof and a plurality of straps transverse said barriers and secured to said barriers and to said casing.

3. A mattress comprising an oblong casing having four conning Walls one of said Walls being provided with a plurality of perforations, barriers extending longitudinally of and secured Within said casing and sub-dividing' said casing into a plurality of compartments, a plurality of straps arranged in opposed pairsA in each said compartment and a pneumatic member larger than said compartment and arranged one in each said compartment and between the straps therein and an inclosing casing for said irst meiitioned casing and means upon said iiiclosing casing and said first mentioned casing for securing saidv casings in operative relation, and means by Which said pneumatic members may be inflated.

Signed at New York city, in the county and State of New York, this 17th day of Sept., i917.
